    Abstract: A battery includes one or more protection layers, applied to one or more foil layers in the battery, which restrict electronic transport across the protection layer based on exposure to particular physical conditions. The protection layer can change from being an electrically conductive layer to being an electrically insulating layer based on the exposure. The protection layer can include a mixture of materials that change state to electrically insulating states based on exposure to various particular physical conditions. A battery can include multiple protection layers that restrict electronic transport based on exposure to different physical conditions. A protection layer applied to a foil layer that is applied to an electrode restricts electronic transport between the foil layer and the electrode based on exposure to the one or more physical conditions. A protection layer located between separate battery cells can restrict electronic transport between portions of separate battery cells.

    Abstract: Batteries according to embodiments of the present technology may include a first battery cell including a first body characterized by a first length and a first width, and a first tab extending from an edge of the first body. The first tab may be characterized by a width less than the first width of the first body. The batteries may also include a second battery cell stacked below the first battery cell. The second battery cell may include a second body characterized by a second length and a second width, and a second tab extending from an edge of the second body. The second tab may be characterized by a width less than the second width of the second body. The second tab may also be characterized by a width greater than the width of the first tab providing an extension of the second tab protruding from below the first tab.

    Abstract: Batteries according to embodiments of the present technology may include a first battery cell including a first current collector. The batteries may include a second battery cell including a second current collector. The second battery cell may be vertically aligned with the first battery cell, and the second current collector may be positioned adjacent the first current collector. The first battery cell and the second battery cell may be electrically coupled together so the first battery cell and the second battery cell transfer current through the cells between the first current collector and the second current collector. The batteries may also include a patterned coupling material disposed between the first battery cell and the second battery cell and joining the first current collector with the second current collector.

    Abstract: A battery cell includes a cathode casing forming all or a majority of the external can of the battery cell. The battery further includes an anode tab covering at least a portion of a face of the battery cell and an insulating layer for electrically isolating the anode tab from the cathode casing. A plurality of such battery cells may be arranged within a battery pack in contact with each other, and may be held in compression. A conduction enhancement layer may be applied between the anode tab of a first cell and the cathode casing of a second cell within the battery pack. One or more heat dissipation elements may be arranged within the battery pack, in contact with the battery cells.
